Phenological phase digital control the growth of plants on the example of spinach

In the introduction it is noted that an important task of the modern industry is the creation of new technologies and devices that allow with a slight increase in material costs to obtain a high yield of vegetable crops.The aim of the study is to increase the yield of vegetable crops on the basis of the technology of digital phenological phase-by-phase control of plant growth.Materials and methods are considered. It is noted that each plant has its own life cycle with certain phases of development. Phenological phases for spinach are given.The results and their discussion, which refers to the preservation of a wide range of crops for which phenological phases are not defined, without affecting the numerical values of environmental and physiological factors in them, and for those where both are defined, the numerical values are not determined for all phases, for example, the temperature and humidity of the substrate, the humidity of the environment and the pH of the nutrient solution for spinach. Recommendations on the application of numerical values of illuminance, spectral composition, salinity of nutrient solutions, etc.In the conclusions it is noted that the use phase-by-phase of numerical values of the factors to control the growth of plants will lead to increased productivity.
